Watsonville, CA-based Applied Motion
Products (AMP) has two new
NEMA 24 frame integrated motors
with dual-port communications for
connecting to the industrial EtherNet/
IP network of a plant or machine.
AMP says that by incorporating two
M12 EtherNet/IP connectors instead
of just one on each axis, the SWM24IP-
3DE integrated stepper motor and
TXM24IP-IDG StepSERVO™ integrated
motor support more efficient
network topologies such as line networks
and daisy-chain connections.

EtherNet/IP network communications
are the widely used protocol for
manufacturing automation applications.
With it, users can control, configure
and query a drive using an open,
standards-based, industrial EtherNet
connection at speeds up to 100
Mbits/s. All drive and motor features
are accessible over the EtherNet/IP
network including over 100 commands
and 130 registers for controlling motion,
I/O, configuration, polling, math,
register manipulation and Q programming.

The additional EtherNet/IP communications
port on the AMP motors allows
cost savings and design
simplification by reducing cables, eliminating
cable trays and downsizing network
switches. For example, in a star
network, every single motor must connect
to the central switch on a dedicated
cable. In a line network using
motors with dual-port communications,
only the closest motor connects
to the switch with the rest connecting
to each other in a daisy-chain configuration.
In addition to shortening cable
runs between motors, only one port is
needed for the entire network which
means a smaller Ethernet switch.

The SWM24IP-3DE and TXM24IP-
1DG integrated motors are IP65 rated
for use in splash-zone and dirty environments.
Each motor features a
NEMA 24 (60-mm) mounting flange
which has the same mounting dimensions
as a NEMA 23 motor but with a
larger shaft to accommodate a higher
torque output.

Both motors include a built-in encoder
for enhanced positioning capabilities.
The SWM24IP-3DE can
perform stall detection and stall prevention
functions for more reliable and
accurate performance than an openloop
motor and in a broader range of
applications.

The TXM24IP-1DG utilizes AMP’s
StepSERVO™ closed-loop stepper technology
to improve the performance of
the step motor with greater acceleration,
increased efficiency and accuracy
as well as decreased motor heating and
noise.
